Volume ray casting, sometimes called volumetric ray casting, volumetric ray tracing, or volume ray marching, is an image-based volume rendering technique. It computes 2D images from 3D volumetric data sets. Volume ray casting, which processes volume data, must not be mistaken with ray casting, which processes surface data.

Famous quotes containing the words volume, ray and/or casting:
“Although volume upon volume is written to prove slavery a very good thing, we never hear of the man who wishes to take the good of it, by being a slave himself.”
—Abraham Lincoln (1809–1865)
“Our reason may prove what it will: our reason is only a feeble ray that has issued from Nature.”

“All we know
Is that we are a little early, that
Today has that special, lapidary
Todayness that the sunlight reproduces
Faithfully in casting twig-shadows on blithe
Sidewalks. No previous day would have been like this.”
—John Ashbery (b. 1927)
